Description
Technical field
The utility model relates to engineering measuring technology field, the measurement of the level foot pin used when particularly relating to a kind of measurement of the level.
Background technology
Levelling pole is the scale of use when carrying out measurement of the level, and measurement of the level foot pin is placed levelling pole and used at turning point place.As shown in Figure 1, existing measurement of the level foot pin adopts the pig iron to cast, and be generally triangular planar plate structure, be provided with the hemisphere summit 5 of a projection in the middle part of triangle flat plate 4, the opposite side of triangle flat plate 4 is provided with three legs 6; During use, leg 6 is inserted ground securely, with anti-sinking, the hemisphere summit 5 of top projection is for erectting levelling pole location and mark turning point.In actual measurement process, the measurement of the level foot pin of this structure often there will be bottom supports 6 upwards when placing, and the phenomena of inversion that semisphere summit 5 is downward, need people's bending to go to overturn righting; Because measurement point position is many, survey crew needs operation of repeatedly bending over, and labour intensity is very large, and have impact on measurement efficiency.
Summary of the invention
The utility model provides a kind of measurement of the level foot pin, and it adopts positive tetrahedron structure, always has a summit upwards, namely have the function of automatic capturing, use very convenient, greatly can alleviate the labour intensity of survey crew after arbitrarily placing, and improves and measures efficiency; Foot pin main body adopts hollow-core construction, conducts oneself with dignity little.
In order to achieve the above object, the utility model realizes by the following technical solutions:
A kind of measurement of the level foot pin, comprise foot pin main body and locating piece, described foot pin main body is positive tetrahedron, and its 4 summits are respectively equipped with the locating piece that outside surface is sphere; The length of side of positive tetrahedron is 100 ~ 200mm, and the diameter of spheroid or ball top cone is 10 ~ 30mm; Foot pin main body is provided with link.
Described foot pin main body is hollow body structure.
Described locating piece is spheroid or ball top cone.
Compared with prior art, the beneficial effects of the utility model are:
Adopt positive tetrahedron structure, always have a summit upwards after arbitrarily placing, namely there is the function of automatic capturing, use very convenient, greatly can alleviate the labour intensity of survey crew, improve and measure efficiency; Foot pin main body adopts hollow-core construction, conducts oneself with dignity little.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
Seeing Fig. 2, is the structural representation of the utility model measurement of the level foot pin.A kind of measurement of the level foot pin of the utility model, comprise foot pin main body and locating piece, described foot pin main body 1 is positive tetrahedron, and its 4 summits are respectively equipped with the locating piece 2 that outside surface is sphere; The length of side of positive tetrahedron is 100 ~ 200mm, and the diameter of spheroid or ball top cone is 10 ~ 30mm; Foot pin main body 1 is provided with link 3.
Described foot pin main body 1 is hollow body structure.
Described locating piece 2 is spheroid or ball top cone.
The method for making of a kind of measurement of the level of the utility model foot pin is as follows:
1) with the steel plate that 3 ~ 4mm is thick, manufacture 4 measure-alike equilateral triangle steel plates, its length of side is 100 ~ 200mm;
2) at the center of equilateral triangle steel plate, each brill 1 diameter is the hole of 8 ~ 12mm;
3) get 1 equilateral triangle steel plate, vertically measure 15 ~ 25mm distance from wherein 1 summit to edge direction, draw the line that is parallel to opposite side; Rule successively in 3 summits, and the distance measured is equal; Then other 3 equilateral triangle steel plates are rule by identical method;
4) along step 3) in the line that pulls, bent to same direction by the drift angle of each equilateral triangle steel plate, bending angle is greater than 90
0, or angle position is removed;
5) by bending or remove 4 triangular steel plate groups after drift angle to rear, the foot pin main body 1 of positive tetrahedron shape is welded into;
6) be that 10 ~ 30mm steel ball or ball top cone are soldered on 4 summits of foot pin main body 1 again by diameter, the sphere side of ball top cone is outside; (as shown in Figure 2 or Figure 3)
7) pass the circular hole on adjacent two faces of positive tetrahedron with iron wire, make link 3, namely measurement of the level foot pin completes.
Following examples are implemented under premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model are not limited to following embodiment.In following embodiment, method therefor is conventional method if no special instructions.
[embodiment]
As shown in Figure 3, a measurement of the level foot pin is made.Concrete steps are as follows:
1) with the steel plate that 3mm is thick, manufacture 4 measure-alike equilateral triangle steel plates, its length of side is 150mm;
2) center of 2 equilateral triangle steel plates wherein, gets out the hole that diameter is 10mm;
3) get 1 equilateral triangle steel plate, vertically measure 20mm distance from wherein 1 summit to edge direction, draw the line that is parallel to opposite side; Rule successively in 3 summits, and the distance measured is equal; Then other 3 equilateral triangle steel plates are rule by identical method;
4) along step 3) in the line that pulls, the angle position of each equilateral triangle steel plate is removed;
5) by removing 4 triangular steel plate groups after drift angle to rear, the foot pin main body 1 of positive tetrahedron shape is welded into; And make 2 equilateral triangle steel plate placed adjacent of wherein having holed;
6) be 30mm by spherical diameter again, the ball top cone of sphere height 15mm is soldered on 4 summits of foot pin main body, and the sphere side of ball top cone is outside;
7) pass the circular hole on adjacent two faces of positive tetrahedron with iron wire, make link 3, namely measurement of the level foot pin completes.
